If you walked away from a 70mph crash, awesome. And if you could drive your truck home, wow! But I don't want your gas bill. There are ways to engineer desired traits that don't involve adding weight. Crash survivability can be enhanced without massive weight increases was my only point. And I AM glad you're OK. I hope the people in the smaller cars are too.
When you hit some crud, the forces on the ski are the same no matter the weight of the ski. If your balance and control is perfect, your skis should not deflect. If you aren't perfect, the force will deflect your skis. Regardless of whether your heavy skis deflect less than my light ones, you still will have to bring that deflection back. If your reaction time is slow, the diverging momentum of the heavy skis will make it harder to bring them back where you want them. Sure, the stronger and more skilled skier may see less of an advantage but for my abilities lighter is an advantage.
Steel is much heavier than aluminum. If the Vist plate were about adding weight, it would be steel (stronger, cheaper, easy to machine and heavier). Doing it my way (light glass filled foamed plastic with lightening holes) is a lot more complex and expensive than using the lightest metal available. If it works, roll with it. Maybe someday they will do a light design. Under a different business name so as not to scare off the die hard weight lovers.
Balancing a ski is fine tuning a design. I doubt that the first iteration of a design had any weights or cutouts in a ski (unless specified by marketing - but that's a different thread).
I'm not sure where you ski but at Squaw bumps form where it is NOT groomed. The snow in the bumps is usually much softer than on the groomers. Most afternoons see a softening of the bumps. Soft snow damps out lots of light ski "quirkyness". Our bumps are a lot different from the groomers.
Competitive bump skiers are awesome. Those courses are firm and fast. And their skis are moving - a lot! Twisting, side to side and up and down. Upper bodies are reasonably quiet. Lots of energy spent moving skis (and boots).
I learned how to ski in college by joining the race team. Maybe my race involvement is a bad idea - the drought in those years was worse than the current drought!
